Combining Angle-Resolved Raman Scattering and Confocal Raman Microscopy for Rationally Designing Two-Dimensional Metallic Arrays as High Performing SERS Substrates

We study the dependence of surface-enhanced Raman scattering from metallic arrays on geometry by angle-resolved Raman spectroscopy and confocal microscopy. It is found that both Raman profile and intensity are strongly dependent on hole size.
